UNIT 5
Computers & Networks
Chapter I. Computers
Part I. TEXT
1. Answer the questions:
1. What does the word “computer” mean?
2. What does the word “to compute” mean?
3. Computers have become an essential part of our lives. Computers are used in different areas of our lives. What do we use them for?
2. Look at the following international words and guess their meaning and check the pronunciation:
Design, sequence, arithmetic, logical, organizing, familiar, calculations, computations, image editing, virtual reality, identification, contactless, media, artificial, mathematical.
3. Here are the words and word combinations you have to learn:
Carry out, accessible, software and hardware’ developers, processing, image editing, virtual reality, a huge impact, transactions, dispense, built-in, face-to-face, the artificial environment, to perform operations.
4. Read and translate the text:
Computers
A computer is a programmable machine designed to automatically carry out a sequence of arithmetic or logical operations. The first use of the word “computer” was recorded in 1613, referring to a person who carried out calculations, or computations, and the word continued with the same meaning until the middle of the 20th century. From the end of the 19th century the word began to take on its more familiar meaning, a machine that carries out computations.
In the beginning, computers were as a big as a large room. It is only later that they have become smaller and smaller, accessible to anyone. This has given way to personal computers. Later software and hardware’ developers created new applications to help users perform many things from word processing and image editing to virtual reality applications.
Now computers have a huge impact on social relations. They have enabled new forms of social interaction, activities and information’s organizing.
In banks, computers store information about the money held by each customer and enable staff to access large databases and to carry out transactions at high speed. They also control ATMs (Automatic Teller Machines), which dispense money to customers by the use of a PIN-protected card (Personal Identification Number). E-commerce has become an essential part of our living activity. Using the online banking service, clients can easily pay checks and transfer money wherever they are. The worldwide payments systems such as PayPal, Visa PayWave, MastercardPayPass, American Express, Google Wallet, Apple Pay, WebMoney, Qiwi and YandexMoney offer customers the service of contactless payments for the goods using smartphones.
Smartphones let us make voice calls, send text, email people and download logos, ringtones or games. With a built-in camera you can send pictures and make video calls in face-to-face mode. New smartphones combine a telephone with web access, video, a games console, an MP3 (Media Player 3) player, a PDA (Personal Digital Assistant) and a GPS (Global Positioning System) navigation system, all in one. And HMD (Head-Mounted Display) such as VR SHINECON, VR Box 2.0 Virtual Reality Glasses, Samsung Gear VR, HTC Vive, Sony PlayStation VR and Oculus Rift allows us to enjoy virtual reality, the artificial environment of the latest video games.
To study well, computers help students to perform mathematical operations and improve their maths skills; they use application software to write essays, projects and to organize and present information. Teachers can create a virtual leaning environment (VLE)[4] for distance education such as Blackboard (http://www.blackboard.com), Moodle (http://moodle.org) and The Bonch-Bruevich Saint-Petersburg State University of Telecommunications’ E-Learning System (http://lms.spbgut.ru).

10. Complete the text using the appropriate tenses (Past Simple, Present Perfect):
Since computers were first introduced to the public in the early 1980's, technology (change) a great deal. The first computers (be) simple machines designed for basic tasks. They (have, not) much memory and they (be, not) very powerful. Early computers were often quite expensive and customers often (pay) thousands of dollars for machines which actually (do) very little. Most computers (be) separate, individual machines used mostly as expensive typewriters or for playing games.
Times (change). Computers (become) powerful machines with very practical applications. Programmers (create) a large selection of useful programs which do everything from teaching foreign languages to bookkeeping. We are still playing video games, but today's games (become) faster, more exciting interactive adventures. Many computer users (get, also) on the Internet and (begin) communicating with other computer users around the world. We (start) to create international communities online. In short, the simple, individual machines of the past (evolve) into an international World Wide Web of knowledge.
